We have a single node cluster for testing.
I just upgraded the cluster to 4.0 by adding a 4.0 server to the v3 node and then doing a fail-over through the UI following these docs:
I did it using the UI and at no point did it ask me to enable query + index server.
Now that I want to try using N1QL I get an error saying no query service enabled. Is there anyway to enable the query & index service on the existing node?
